I have lived in Chang 'an for six years ... including three years in Bian Xiao ... (currently in Zhuhai).
Do you know Bian Xiao Square? There is an internet cafe opposite, called e-time. The internet speed is good and cheap. Not far from the tunnel to the punching machine, there is also a home called Forgetting (Dream World). There is also an Internet cafe further away from Chang 'an Post Office, near Fu 'an dormitory area. . . .
I hope you are satisfied. . .
